목적: The present study aims to evaluate clinical characteristics of CXPA and PA, and to identify factors associated with differential diagnosis of these conditions. 방법:We reviewed the medical records of 6 CXPA and 127 PA patients treated surgically at our institution from 2008 to 2024. 결과:Univariate analysis showed significant differences in factors of spontaneous pain (p = 0.044), facial nerve palsy (p = 0.045), and subjective enlargement (p < 0.01) between CXPA and PA patients. On magnetic resonance imaging (MRI) findings, proportions of masses with irregular margins, localization in deep lobe, and low levels of apparent diffusion co-efficient (ADC) were significantly higher among patients with CXPA than among those with PA (p < 0.01, p = 0.048, and p < 0.01, respectively). Multivariate analysis identified spontaneous pain and masses with irregular margins associated with CXPA (p = 0.047, p = 0.013). 결론:A symptom of spontaneous pain and masses with irregular margins could be a factor suggesting CXPA rather than PA. Low levels of ADC indicated the possibility of CXPA. Regarding the difference in ADC values between CXPA and PA patients, accumulating a larger number of these cases would be necessary for more accurate analysis.
